Determining the best interchange for Saturated Intersection with traffic lights (Case Study: Dizel Abad Intersection, Kermanshah, Iran)

Mohammadali Esfandiarifar, Seyed Mahdi Sajjadi, Seyyed Amir Hossein Beheshty


One of the main problems of metropolitan cities in traffic topics is the Intersection with traffic light. One of the weaknesses of these intersections is the creation of long queues due to left-turn movements during the peak hours of daily traffic, which reduces speed. The flow of traffic as well as the level of service decline. Therefore, optimizing cross-sectional intersections in order to reduce the delay time and production of pollutants and fuel consumption is of great importance. The purpose of this study is to examine and compare the results of converting a level crossing (case study of Dizel Abad intersection of Kermanshah, Iran) to a interchange using the Aimsun software simulator. The scenarios used in this study include the present status of the intersection of the study, Cloverleaf Interchange, semi-directional interchange, U-turn Interchange and U-Turn Interchange with a specific right-turn path, The final results show that the best interchange among considered interchange will be semi-directional interchange so this interchange will reduce around 81% in travel time and 68% in travel speed.
